AC/DC, one of the most enduring and influential rock bands in history, was formed in 1973 by brothers Angus and Malcolm Young in Sydney, Australia. Named after both a Victorian-era term for alternating current/direct current (AC/DC) and a rhythm slash chord combo from Chuck Berry's "Too Much Monkey Business," the band has been known for their distinctive sound, energetic performances, and lasting power. The group's classic lineup, which featured Angus Young on lead guitar, Malcolm Young on rhythm guitar (with both brothers known for their schoolboy uniform), Bon Scott on lead vocals, Phil Rudd on drums, and Cliff Williams on bass, became a template for hard rock bands around the world. AC/DC's music is characterized by its blues-inspired hard rock sound, simple yet memorable melodies, and anthemic choruses. Their lyrics often revolve around fundamental themes such as love, women, and rock and roll, delivered with a swagger and a sense of humor that has endeared them to audiences globally. The band's breakout album, "Highway to Hell" (1979), was a commercial success and a critical showcase of their raw energy, solidifying their status as one of the leading bands in hard rock. Following Scott's tragic death in 1980, AC/DC found a suitable replacement in Brian Johnson, who helped the band achieve even greater international fame with the epochal "Back in Black" (1980), which became one of the best-selling albums of all time. Throughout the '80s and beyond, AC/DC continued to dominate the rock scene with consistent album releases, iconic music videos, and worldwide tours. Their ability to maintain a consistent style while evolving within their genre has made them a timeless band whose influence on rock music is immeasurable.
